Abstract
Values of the thermal-conductivity coefficient of specimens of the frame insulation manufactured from pre- and unimpregnated, mica-containing tapes are determined. It is established that the tape structure, temperature, epoxy binding content, and type of packing materials (filling compounds) have an effect on the thermal conductivity of the insulation system of the stator winding of turbogenerators with air cooling.
